Display with backlight, hold, sleep modes. Large direct-reading display of CHANCE Digital Phasing Testers easily determine phase relationships and approximate voltage, line-to-line or line-to-ground. Each tester consists of two fiberglass poles with end fittings threaded for interchangeable probes. The probe fittings couple with a high-impedance component encased in each pole. To complete the test circuit, a 22-foot length of insulated flexible cable stores on the reel affixed to one pole and connects to the electronic display module on the other pole. Simple to operate, the tester attaches to two 6-foot Epoxiglas® insulating universal handles (included in each kit for proper working clearances). Then the probes can be brought into contact with the conductors appropriate for the tester to display phase-to-phase or phase-to-ground voltage.
